CONSTITUTION:A N type single-crystal Si island 1 is surrounded with a separation insulating film 2 so as to be provided with dielectric separation, and its outside is protected by a poly- crystal Si layer 3. An N+ burial layer 4 is disposed so as to serve as an N type highconcentration impurity layer on side and bottom parts of the singlecrystal Si island 1. A part 5 is a P type impurity region which is disposed in the N type single-crystal Si island 1 isolatedly from the N<+> burial layer 4. A part 6 is a N type impurity region which is positioned on a flat bottom surface of the P type impurity region 5 and has a junction surface 7. When a voltage is applied to metallic electrodes 11 and 12 made to serve as positive and negative electrodes, respectively, a reverse bias voltage is applied across the P type impurity region 5 and the peripheral N type region. As the voltage is further increased, breakdown of a zenor diode occurs uniformly on a flat junction surface 7 which is a boundary formed in the highest concentration of N type impurity between the P type impurity region 5 end the N type region.

Abstract: PROBLEM TO BE SOLVED: To simplify operation, decrease the number of bits of an operation result, and to obtain efficiency, quick response, and high display quality by imposing pulse-width modulation on a gradation signal while scanning more than one scanning lines at the same time. SOLUTION: Two registers 51 and 52 and one function computing element (MLSALU) 53 are provided, and one selectior period is divided into two periods; and pixel data of three lines for an upper screen are transferred first to the register 51 to operate pixel data for a lower screen of a previous line by the function computing element 53 and in the latter half time, pixel data of three lines of a next lower screen are transferred to the register 52 to operate pixel data for the upper screen of the line stored in the register 51 by the function computing element 53. Thus, a control circuit 5 divides the selection period of a scanning circuit into more than one parts, and operations by divided screens of liquid crystal cells are performed in a divided selection period to make the processing of the control circuit 5 relatively slow and make the arithmetic circuit small.

Title: Dynamic assignment for audio and image compression
Inventor: JAVITT JOEL I
IPC: H04L12/56
Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To avoid the service of the system to the user from being blocked and to maintain the quality of communication by controlling a valid system capacity dynamically so as to increase it when traffic is at a peak and to decrease it when the traffic is decreased. SOLUTION: A communication system 10 has a plurality of users 14 coupled with a network 11 through a switch 13 and provides N-sets of channels to a provided service area. A network controller 12 decides a probability based on a channel operating state that the service to a potential user 14 is blocked, compresses a voice of a selected channel when the service block probability exceeds a permissible value so as to, increase the system capacity, that is, number of calls to be handled per unit time. When the service blocking probability is a specified value or below, voice compression is reduced or relieved to improve the voice quality. Thus, the valid capacity of the communication system 10 and the performance of voice quality are improved.

Title: Combustion chamber of engine
Inventor: HATSUHIRA TSUGIO
IPC: F02B23/08
Filed: 1988-11-29
Abstract: PURPOSE:To make it possible to materialize a compact combustion chamber without knocking by setting the squish area formed along the peripheral edge of a cylinder bore in such a way that its suction port side becomes larger than its exhaust port side. CONSTITUTION:No.1 dome 5a and No.2 dome 5b having a diameter larger than the dome 5a are formed around the suction port 8 and exhaust port 9 of a cylinder head side engine combustion chamber 5, respectively. Squish areas, located outside each dome 5a, 5b and formed along the peripheral edge of a cylinder bore 3, are set in such a manner that a suction side squish area 7a becomes larger than an exhaust side squish area 7b. Since the setting sufficiently enhances the combustion speed of the suction side fuel-air mixture with a lower temperature, the combination of the two sets of domes 5a, 5b makes it possible to materialize a compact shape for the combustion chamber 5 by drawing it close to a spherical form as much as possible. The setting also allows to obtain a high efficiency without knocking.
